A TEEN smacked his father in the head with a spanner in an unprovoked attack, leaving him with a nasty gash which required stapling.
David Donald Lloyd Laurie, 18, faced Mackay Magistrates Court on Monday, pleading guilty to assault occasioning bodily harm on April 25.
Prosecutor Sheena Hayes said Laurie - who moved to Mackay after the attack in Toowoomba - had no prior criminal history before the attack.
She described the assault on the "father of the defendant" as without provocation and mentioned there was difficulties finding similar cases for precedent.
Further, Ms Hayes said Laurie's attack left his father with a 5cm laceration to the back of his head, which was patched up with staples.
The prosecutor indicated an appropriate sentence for Laurie would be "probation through to immediate parole".
Following Ms Hayes' submissions, Magistrate Damien Dwyer√ cited a different case and mentioned prison was not out of the question.
"The circumstances surrounding the commission of this is he picked up a spanner and smacked his father over the head with it," he said.
The magistrate described the assault as "severe" and aggravated by the use of a weapon.
Defence solicitor Aaron Sellentin described Laurie as an unemployed father who was on Centrelink benefits, following a "disjointed upbringing, with his father who has alcoholic issues".
Mr Sellentin said Laurie had a solid work history as a kitchenhand, labourer and cattle station hand.
"He (Laurie) was living with his father and worked for the same employer as his father at the time of this offence," he said.
"He left Toowoomba about two days after the offence occurred and relocated to Mackay for a fresh start.
"He's currently living with his partner in youth accommodation ... prior to this he was couch surfing."
Mr Sellentin added Laurie had been diagnosed with depression and anxiety and had sought help with Anglicare for anger management.
"He does want to deal with the consequences and move on with his life, your honour," he said.
"He has shown remorse and cooperation with police."
Mr Sellentin, who noted Laurie had made a timely plea, argued probation was an appropriate sentence.
The case was adjourned for a decision on July 17.
UPDATE: Laurie was sentenced to probation for a year and ordered to complete 150 hours of community service when his case returned to court.
